"Soo.... whaddaya say, bro?" Riley asked, giving his little brother Joey a coy look as he rubbed one of the younger goat's thighs. "Wanna have some 'big-boy fun' with me?~" 

The goat flashed a toothy grin as he watched his little brother squirm awkwardly on the bed. The two of them were alone together for the weekend, their parents away on a trip. Riley could feel his loins stir with arousal as his eyes danced over Joey's young, unblemished body. His gaze settled on the smaller goat's package, a slight bulge poking out from his shorts. Riley couldn't help but lick his lips hungrily at the thought of how Joey's cute little cock would taste in his mouth.

But it was Joey's virgin asshole that really had Riley's cock twitching with excitement. The thought of sliding his member inside the younger goat's untouched hole, making him whimper and moan with pleasure, sent shivers down the older goat's spine.

Riley leaned forward, his mouth inches away from Joey's ear, as he whispered seductively. "Just say the word, Joey.... and I'll make you feel things you never knew were possible."

Joey fidgeted awkwardly as Riley's hands started to explore his body. The young goat could feel his cock getting hard as his big brother stroked and teased his furry sheath through his shorts. It was a new, exciting feeling, but at the same time Joey was also a little nervous.

"Well? Are you in?" Riley pressed, eager to get a response.

Joey hesitated for a moment, biting his lip, then nodded slowly. "O-okay...let's do it. But....promise we won't tell Mom or Dad, okay? They won't let me have video games again if they find out!"
The older goat's expression became reassuring as he spoke softly to his little brother. "Don't worry, it'll be our secret. I promise."

With that, Riley grabbed the bottom of Joey's shirt and lifted it up over the boy's head. He couldn't help but grin wide when he saw his brother's soft, fuzzy nipples, already erect from his touch. Taking things slow so as not to scare his younger sibling off, the horny goat bent his head down and started to gently lick one of those delicious nubs.

Joey shuddered lightly under the touch, letting out a gasp as Riley continued to suckle on him. As much as the younger boy hated to admit, it felt good! Really, really good! In fact, the sensual warmth of Riley's tongue swirling around his nipple was quickly driving the youth to a state of near delirium, especially when his older brother would pull back and then dart forward to lash at his sensitive little tit with quick flicks. Joey let out a loud, involuntary bleat as his shaft started to stiffen, which just seemed to further encourage the elder.

Riley noticed this, and snickered slightly before moving his free paw lower towards his prize. Upon reaching Joey's trousers, he paused and looked back into his brother's flushed face. "You alright there, Joey?" the older buck asked, a hint of mischief in his voice.

The small goat could only nod feebly, his mouth opening and closing a few times, lost for words. He gave Riley an urgent look as he realized what his brother was up to.

With a chuckle and a wicked grin, Riley got to his feet and kneeled in front of the younger boy. He gripped Joey's pants in both paws, looking him dead in the eyes with a questioning stare. The two stared at each other like that for a minute, their breathing heavy, before finally Joey spoke up.

"Do it... please, Rye," the boy pleaded, his voice barely above a whisper.

Riley grinned nastily, sending a tingle down Joey's back.

"Gladly..."

Pulling downward hard, the older goat ripped his little brother's clothing clean off his body, revealing the preteen's slender frame. As the pieces hit the floor, a musk invaded Riley's nostrils that was a thousand times more intense than any sweat the small goat had ever smelled before. The odor made him giddy with excitement, almost causing him to swoon.

"My my," the horny goat snorted, a predatory glint appearing in his pupils. "Aren't you a bit more built than the last time I've seen you naked?"

His large black shaft fully extended, throbbing painfully with a need to release, he towered over his tiny brother's form. "Don't go looking at me with that dreamy face. It's been too long since my balls have been drained, so you have no idea what I'm about to put you through, and no choice in the matter," Riley informed. He wanted to jump right in, but needed a clear answer from his baby brother.

"Yes, please, do it big brother," the boy goat whispered softly. "Make me feel good."

Smiling broadly, the horny elder slowly pushed himself towards his brother. Soon, he was nestled behind his little brother's bare butt. Riley placed his hands on the back of Joey's warm thighs, slowly spreading his legs wide apart. Gazing intently, his hungry eyes took in the boy's lithe, smooth frame.

The youngster could feel the intensity of the larger goat's stare as his nether region was examined closely. It was nerve wracking to say the least and his whole body trembled uncontrollably from being completely naked in front of his sibling, never having done something quite like that before.

The eldest brother grinned, giving Joey a wink. "Just relax...and everything'll work out just fine," he purred in a comforting tone of voice. He trailed finger gently up Joey's inner thigh, and slowly across the bottom edge of his ballsack.

"Woah!" Joey breathed sharply at the alien contact. His testicles suddenly throbbed as his heart rate skyrocketed. A wave of excitement washed over him as Riley began teasing his orbs, which were swiftly filling with seed. "This... This is kinda different!" the pup whimpered, biting back a moan.

"Hmmm... Good different, I take it?" the adult goat cooed, letting his palm knead those baubles, fondling his brother's fruits with practiced care.

"Mmmhhmm..." was all the horny kid could think to say in reply, nodding his head slowly.

After several minutes of working over his younger brother's sacks, Riley's fingers strayed up towards the plump, hot furry cheeks of his little brother's cute, tantalizing booty. Running them over those fat rump pillows with delicate care, Riley dug into those lovely fats. "Oh... This is just amazing Joey... You look so delicious and fuckable. I could just eat you up~" the goat elder declared before spreading those big, bubble butt buns and showing off Joey's tight, furry virgin hole, his pink entrance visibly puckering with an instinctual need to have the elder's rod penetrate it.

Joey could feel his pulse racing, and his mouth suddenly went dry. He wasn't sure whether the naughty feelings building up inside him were because his sibling had just spoken to him in such a dirty, inappropriate manner, or because a perverted part of his own psyche was getting aroused by it. In the heat of the moment, all that mattered was that Joey wanted Riley's dick inside his bottom and he would do anything to have it.

"Goddamn Joey, what a beautiful hole," Riley murmured in awe, staring intensely at the preteen boy's cute, tight furry ass hole. He leaned in closer and closer, the stench of Joey's developing preteen-musk hitting his nostrils hard and making his rock-hard cock strain against his own underwear even harder. Finally, Riley's tongue peeked out of his mouth, latching onto his little brother's beautiful ring.

Joey nearly jolted off the bed as that hot wet tongue swabbed over his untouched hole. "UWAHHH! O-ooh!" the small goat moaned. Tendrils of excitement shot throughout his small body, emanating from his well-played hole. All thoughts left his head as his mind was filled only with Riley and his magical, tongue-wielding skills. The youngster had never felt something so incredible before in his life.

Seeing his brother's positive response, the young goat buck became more bold in his advances, hungrily slapping his slippery appendage all over and inside Joey's sexy booty.

"Wow....Riley...," the youth uttered, almost completely overcome by bliss. Joey reached down and grasped his erection, unable to resist the overwhelming lust now consuming him. It had already leaked a bit, staining the covers. "Y-You're r-really good with y-your tongue...."

Joey squirmed as he felt his brother's tongue slowly poke his tiny butthole, sending a tingly feeling straight down to his little cock. Joey never thought in a million years he'd be getting his butt licked, especially by his own brother! The thought made him even more nervous, yet he couldn't help but feel an intense throbbing between his legs.

Riley continued kissing and licking Joey's hole, savoring every drop of the sweet, musky flavor that emanated from his body. Riley was amazed at the way Joey squirmed and groaned, knowing that his brother was feeling just as much pleasure as himself. It made Riley's 9-inch hard-on throb even harder, and the thought of shoving his fat, veiny cock into his own brother's tight little hole drove Riley wild with lust.

Riley rose up onto his knees, positioning himself behind his little brother as his dick pressed against Joey's tight ring. "Do you want me to fuck you now?" Riley asked, his heart pounding in his chest.

"I dunno, it looks so big," Joey whimpered nervously. He didn't want to admit it, but the thought of being penetrated was a little scary. But Joey was determined to be the good, helpful, brave little brother like he always was, and decided there was nothing he couldn't do for Riley.

"It's okay, Joey," Riley reassured his brother. He took hold of Joey's shoulders and gently pulled him backwards, his plump young cock-head popping into Joey's entrance with relative ease. A soft moan escaped Joey's lips as his little hole slowly adjusted to accommodate Riley's massive cock.

"Ouch, Rye!" Joey whined in response. He could feel his little hole stretch wide open around his brother's hard, throbbing flesh as it forced itself into him inch by inch. He began to cry out in pain until suddenly... he felt a tingling sensation! That spot where Riley had his mouth felt so tingly, but in the best kind of way!

Joey began to wonder if the hot feeling in his little tummy was more than just Riley's meat. He tried pushing himself back towards Riley, working through the slight pain in order to experience this new pleasurable sensation.

With his little brother's help, Riley was able to work most of his massive tool inside his little sibling's snug butthole, and he moaned lowly at how fucking good his little brother's butt felt around his cock.

Riley had done it with other little boys before, but Joey was definitely the best ass yet. And the fact that he was so pure and innocent and so sweet made Riley even hornier. Joey looked so good, on all fours, his soft, light, delicate little body with smooth legs and round, supple butt cheeks and his short blonde hair and beautiful baby blues made Riley want to fill that tiny ass with his sweet, hot seed.

Joey's face was red. His bottom was hot and full, and felt oddly nice. He could feel Riley throbbing inside of him, which made him smile. Riley smiled as well, looking into his little brother's innocent baby blue eyes. Then without hesitation, Riley began slowly thrusting himself in and out of Joey's virgin hole, each motion getting smoother and quicker with the aid of the leftover lube.

"Ah, shit, fuck, ohhh," Riley groaned, leaning over his little brother's small body, grabbing onto his hips and pulling him back against his manhood.
Riley moved slowly but deep, grunting and groaning as his balls swung around below.

Joey clenched his eyes shut, not being able to handle the new and confusing feelings welling up inside his chest and belly. His mouth was agape and drool began to fall from his lips, rolling down his chin. His hands were clenched in little fists and he felt an electric surge that made him jump when Riley thrust his meat further into his asshole than before.

"Guh--Ri...yeah!" Joey screamed out in pleasure and surprise as his small little prick pulsed and began shooting a load onto the blanket below.

Riley shuddered slightly when he felt Joey clench around his length, but continued thrusting at an increasing pace. The warm sensation around his cock drove him wild, making him thrust even harder and quicker.

"Oh yes," Riley moaned in a high voice, getting close to climax as he dug his nails into the young boy's plump bottom, pummelling his brother's asshole so rough that a faint slapping noise echoed off the walls of the room. "You like that, baby?" Riley teased.

The whole bedroom was filled with their erotic cries, their panting and groaning getting more intense by the second. Riley could feel his cum rising in his hard dick. All his thoughts and feelings were completely drowned out by his own high-pitched moans and screams of pure pleasure and satisfaction. It felt too good and he needed to bust, soon!

"Unf! Fuck! I'm going to shoot my huge load inside you, Joey, do you want that?"

Joey screamed "Yes!" with no hesitation. He loved the feeling and he needed more of it, too. He loved feeling his brother's manhood pierce him, fill his belly with warm semen. He wanted the moment to last forever, his small frame jerking and trembling as another small squirt of his clear, pearly pre-cum shot out from his tip.

But he knew he couldn't last much longer, with the heat and pulsating and tightening building deep inside his pelvis, until he was yelling out in pure ecstasy. "RYEEEEE!!!" Joey cried, releasing a thick spurt of creamy cum.

Joey clenched down on his brother's tool, hard enough to drive Riley over the edge and he came at full force. Riley cried as his cum started to spurt inside his brother, "Yes, yeeeeees, Oh, god, your little ass is so good, Joey!" he grunted and slammed hard once more. His fingers gripped into the flesh of the little bottom, leaving small white lines on the flushed skin.

Joey's young butt squeezed Riley's cock perfectly, and soon they were both lying side-by-side on their wet blanket. Their hearts pounded and they breathed heavily as the post-orgasmic feelings sunk in. Riley wrapped a hairy arm around his small brother and Joey cuddled right into his warm, naked body.

"Thanks, Rye. I love you," said Joey, wiping a string of drool from his cheek. He wasn't sure if he was supposed to kiss Riley after the sex, so he didn't. But it didn't matter anyways because Riley would've never guessed little Joey felt any more love for him then normal brotherly love, because his mind was preoccupied. He was thinking about his brother's hot hole, the noises his brother made, the way his brother's little, hairless testicles felt pressed against his palm. His brother. His little brother.

"Do it again!" Joey said, suddenly jumping up out of his brother's warm embrace to stand over him and straddling his strong thighs.

Joey's growing penis hung over Riley's messy, still half-hard member, and his swollen lips looked inviting to the young adult.

"Just wait, you'll get your fill, you insatiable little fuck," he chuckled, and scooped up his baby bro into a big hug.

Joey blushed again, and felt the soft prickles of the hair on Riley's chest poke against his belly. Riley smelled musky and manly, and Joey was immediately hard again.

"Your cute ass'll be a total mess when we're done," Riley muttered, his voice deep and almost ominous. He looked into his brother's eyes with a devious expression and raised his hips, making their crotches brush together. "And everyone'll know just who owns it~..." he said in a sing-song voice.

Joey gulped at the prospect of being his big brother's little toy... but he also couldn't deny that it also excited him too. He gave Riley a small nod and Riley chuckled, grinning lewdly and licking his lips in eager anticipation.

"Greedy boy."
